Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but not as a basis for limiting the present invention.

The embodiment of the present application: a cold-formed thin-walled steel light-weight concrete composite integrated wall panel structure, as shown in the accompanying drawings 1-10, includes a wall panel body 1 cast with light concrete, and the left side of the wall panel body 1 is The concave shaped steel 3 is connected by end casting, and the convex shaped steel 2 is connected by casting at the right end of the wall panel body 1 . When the wall panel is installed at the leftmost end, the left end of the wall panel body 1 is a plane structure as shown in FIG. 9 at this time; when the wall panel is installed at the rightmost end, the The right end, as shown in Figure 10, is a plane structure. The protruding parts 5 provided on the convex shaped steel 2 are structurally corresponding to the concave parts 6 provided on the concave shaped steel 3 . An installation pipe 7 is arranged between the two side walls of the protruding part 5, and the two ends of the installation pipe 7 are respectively fixedly connected with the inner surface of the side wall of the protruding part 5. Two screws 8 are installed in the installation pipe 7 facing away. A spring 9 is arranged between the two screws 8. The shafts of the two screws 8 pass through the protruding part 5 and then extend to the outside of the protruding part 5 under the elastic force of the spring 9, and the protruding hole is smaller than the nut of the screw 8. , so as to prevent the lower screw 8 from falling out of the installation tube 7 around the spring 9 . The inner surfaces of the two side walls of the recessed portion 6 are respectively provided with multiple sets of horizontally arranged sleeves 10, each group includes two symmetrically arranged sleeves 10, and each sleeve 10 is connected to the side wall of the recessed portion 6. End connected to the outside.

The manufacture and installation of the entire wall panel includes the following steps:

1. As shown in Figure 6, firstly, the cold-formed thin-walled section steel at the edge of the wall panel body 1 is produced into a specific size and shape. One edge of the wall panel is concave, that is, the concave section steel 3, and the other wall The edge of one side of the plate is convex, that is, convex shaped steel 2 . And fix the screw 8 and the spring 9 on the installation pipe 7 of the convex steel 2 at the convex steel 2, so as to avoid the concrete entering the installation pipe 7 when the concrete is poured in the later stage, and the screw 8 and the spring 9 are solidified, resulting in the later stage. Screw 8 and spring 9 cannot be used during installation. A set of installation pipes 7, screw rods 8 and springs 9 are arranged at intervals along the convex section steel 2;

Use the casing 10 at the position corresponding to the concave shaped steel 3 of the other wall panel to reserve holes in advance before the wall panel is poured. Then light concrete is poured, and finally the structural wall panel shown in Figure 1, Figure 9 or Figure 10 is obtained.

2. As shown in Figure 7, then hoist and install the wall panel. When the concave section steel 3 and the convex section steel 2 are close to each other, use a tool to press the end of the screw 8, so that the screw 8 compresses the spring 9 and moves toward the inside of the installation tube 7. Move to make the concave section steel 3 fit the convex section steel 2, and the spring 9 rebounds when the screw 8 and the hole reserved on the concave section steel 3 are in the same position, so that the screw 8 enters the hole of the concave section steel 3 to realize "self-locking". ". In order to achieve rapid "self-locking", the ends of the two adjacent wall panels should be kept flush. At this time, the corresponding screw 8 and the corresponding reserved holes are on the same level. After moving one wall panel horizontally, the screw can be guaranteed. 8 Snap into the reserved hole.

3. As shown in Figure 8, after the "self-locking" of the wall panel is completed, the connecting seam of the wall panel is processed, and the entire installation process is completed.

Both ends of the convex section steel 2 and the concave section steel 3 are provided with connecting plates 4 extending toward the wall panel body 1 . The convex section steel 2 and the concave section steel 3 are firmly connected with the poured concrete, and the integrity is better.

The top surface of the convex-shaped steel 2 on both sides of the protruding part 5 is fixedly provided with an elastic material layer 11, and the elastic material layer 11 can be an elastic material such as asphalt hemp, which can prevent the adjacent 2 blocks. When the wallboard surface touches, the wallboard surface is damaged. The outer side of the elastic material layer 11 is provided with a waterproof blocking material 12, and the waterproof blocking material 12 can be a foamed rubber rod or other waterproof blocking material to achieve waterproof effect.

When the two adjacent wall panels are connected, that is, during the third step, the refractory building sealant 13 is injected on the outside of the waterproof sealing material 12, and the jointing agent 14 consistent with the wall paint is used on the outermost side for jointing.

The installation pipes 7, the screw rods 8, the springs 9 and the sleeves 10 are provided in a plurality along the height direction of the wall panel body 1, and the distance between the two adjacent installation pipes 7 or the two sleeves 10 is about 1m, and the Better "self-locking" effect.

The cross section of the protruding part 5 and the recessed part 6 is an isosceles trapezoid structure which is expanded obliquely to the outside, and this structure can realize the quick engagement of the protruding part 5 and the recessed part 6 .

The protruding part 5 and the concave part 6 are respectively arranged in the middle position of the convex shaped steel 2 and the concave shaped steel 3 . Ensure that the structural performance of the walls on both sides of the protruding part 5 and the concave part 6 is consistent.
